Compare Endorphin Pro by generation
The Endorphin Pro is Saucony's carbon-plated road-racing family. Start with your planned race and preferred fit, then open the exact generation. Remaining Pro 4 and Pro 5 listings have separate constructions and size selections.
Pro 5 and Speed 6 serve different sessions
Pro 5 combines PWRRUN PB and Super Critical PWRRUN HG with a slotted carbon plate. Speed 6 uses PWRRUN PBX and a nylon plate for faster training. Compare both in motion at the pace you intend to use; a plate material alone cannot tell you which shoe feels better on your foot.

Check toe clearance, midfoot pressure and heel hold with your running socks. Try a controlled turn and the pace you expect to run. Each product keeps its own generation, gender, width and available size options.
